Half a year ago, I received a call from Mr. Chen, a well-known door manufacturer in Guangzhou. He said that the brush strip for roller doors provided by a brush factory outside the province, but this year has received feedback from many dealers that it is easy to lose filament and lack of tensile strength. There has been no improvement in the brush suppliers outside this province, and the problem still exists. Now Mr. Chen is preparing to develop a new brush supplier locally, so he has found AOQUN.

After understanding Mr. Chen’s needs, I introduced to Mr. Chen that the standard of pulling force on the brush strip for roller doors is: the tensile strength of the strip brush length 10mm, the bottom width ≥3mm, the pulling force ≥6kg, the bottom width ≥4mm, tensile force ≥10kg, when the bottom width <3mm or the base metal sheet thickness <0.5mm and the required gross thickness is large, it should be agreed according to the actual situation. This time, according to Mr. Chen’s acceptance requirements for the pull, we made a corresponding pull test on the brush strip for roller doors. It is required that the tensile force of about 200 filaments is greater than or equal to 10 kg. As a result, the tensile force we applied is greater than 10 kg, but the filament does not have any pulling action. I also invited Mr. Chen to visit the factory and also personally do this tensile test in front of him.

After a thorough understanding of the AOQUN, Mr. Chen gave full affirmation to AOQUN. Finally, Mr. Chen placed an order for the 1000-meter brush strip for roller doors on the AOQUN. At the same time, Mr. Chen's customers are very satisfied with the brush products provided by Aoqun.
